Description

The calendarLabel property is not read by the screen reader and is not assigned in the DOM.
I also searched in the source code of the calendar component and it seems that it exists only in the documentation, and in the html or ts code it is not assigned anywhere.

Reproduction

Steps to reproduce:

1. Open stackblitz example
2. Open NVDA screen reader (or other screen reader)
3. Focus the datepicker icon
4. Press 'enter' key to open the calendar popup

Expected Behavior

The calendarLabel property should be read by the screen reader and should exist in the DOM.

Actual Behavior

The calendarLabel property is not read by the screen reader and is not assigned in the DOM.
